[Elecraft] Re: Help with Birdie (not "tweet tweet!")

It's easy to tell if one of the 4 MHz oscillators is the source. Just =
touch
the frequency adjustment trimmer and see if the birdie shifts. Your =
finger
will add enough capacitance to make it move.=20

If so, you can move either oscillator with no deleterious effects right =
now.
The frequency of the oscillator on the KPA100 is not critical at any =
time,
according to the Elecraft documentation.=20

The frequency of the oscillator on the Control Board provides the time =
base
for the frequency counter function that you use when running CAL FIL or =
CAL
PLL, but otherwise it is not critical. So you could move it, provided =
you
remembered to put it back before you run CAL FIL or CAL PLL for some =
reason.


Of course, moving either oscillator down in frequency will put them in =
the
75 meter phone band.

Further to my original message (see below) - could it be the 7th =
harmonic of
the 4 Mhz oscillator?? Is so, what exactly does this oscillator do? And,
would it be harmful to move it down to, say, 3.999 - so that any =
harmonics
would fall outside the Ham Bands??

Any replies??
